The Trade Services bundle is a small collection of services for handling trade streams. A trade stream is an event-based representation of all the trades that an application – or the organization running the application – was involved in. This contrasts with a tick stream, which is a representation of all the trades occurring on a particular venue between all participants. Trade events are typically generated by order routing – as opposed to market data – adapters and will contain a much richer set of fields than the corresponding tick events.
